New Network Woes

My local subnet is 192.168.0.1 but I have several local subnets that show up as new networks in zone alarm. I try to remove them but it keeps complaining that you cant delete an active network. The new networks are 192.168.223.0, 192.168.150.0 and 169.254.0.0. Any ideas why these local subnets are popping up? Any suggestion on deleting them or at least making them restricted network and denying them all access?
